Ain't NOTHING like the real thing. Unless they have TRULY found Artificial Intelligence, that toddling robot doesn't have ANYTHING on the natural lawyers built into toddler's. It's AMAZING how quickly they figure out the loopholes in home rules.
And - let me get this straight - they build a (probably multi-mullion-dollar) SIMULATOR to figure out how a child learns? Good grief, don't we have enough real-life examples running - er toddling - around? Try asking some PARENTS. What are the researchers going to do, ASK the scary little machine how it learned to say "no!" when it's told "time for bed, sweetie."
